For voice you could get away with a lower quality ogg and/or resampling to a lower sample rate (digital telephony itself uses 8kHz) For the ultimate in voce compression however, there are free GSM compression/decompresison tools. In debian the gsm-utils pachage seems to the the thing you need, no doubt will pull in all the various libgsm* packages too. I haven't used it, but if you can get it to do what you want you waon't get better voce compression. > what type file will it be that is easily platform independent Ogg vorbis is quite portable. Don't know about the GSM tools. -- Anahata anahata@xxxxxxxxxxxxxx -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
